"It's indescribable! No matter how long we look at this, our brains are not processing this image in front of us. It is absolutely spectacular, surreal—there's no adjectives. I'm gonna need to invent some new ones to describe what we're looking out this window."

So today the IAU officially renamed Charon's iconic north pole from "Mordor Macula" to "Neverland Regio"… Not sure why it's renamed now, even though "Mordor" has been in scientific use for over a decade. Everyone I've talked to hates the new name lmao. This'll take time getting used to…

From high-impact weather events to stratus clouds dancing over the open ocean, this year was filled with impressive satellite imagery. We look back on the most compelling satellite views of 2025. 1) Mesovortices slosh within Hurricane Melissa’s ferocious eye (October 8).

My favourites from today are: hot Jupiter companion occurrence rate arxiv.org/abs/2601.13302, primodial superearth population arxiv.org/abs/2601.13480, clouds on T/Y dwarfs arxiv.org/abs/2601.12575, and a visit to HD 166620 arxiv.org/abs/2601.11853

The Occurrence Rate of Nearby Planetary Companions to Hot Jupiters

Of the > 500 confirmed transiting hot jupiters and approximately 2000 additional candidates today, only ten are known to have nearby companion planets. The survival of nearby companions means that the...

Inspired by my conversation with @gnollified.bsky.social elsewhere, I decided to draw a young Triton with thick atmosphere...took it down, and corrected it. Presenting version 2! bsky.app/profile/gnol... #art #astronomy #space #SolarSystem #planet #moon #Triton #Neptune

This artwork depicts what Neptune's moon Triton might have looked like when it was younger. Triton is generally believed to originate as a dwarf planet like Pluto, before being captured by Neptune. The capture would likely have placed Triton in a highly eccentric orbit. Intense heating ensued as Neptune pulls and stretches the moon's materials; this tidal heating may be enough to melt the moon's interior and triggering a full differentiation separating iron from silicate, maintain subsurface ocean under a thin ice crust, and cause volatile substances like nitrogen or methane to sublimate, forming an atmosphere. This atmosphere would be quite strange; as heat emanates from the interior, the upper atmosphere remains cold enough that methane and eventually nitrogen would condense, producing high altitude clouds across the entire planet. Over time, this atmosphere would be lost, leaving behind a thin atmosphere as seen on Triton today. During this time, formation heat probably caused Neptune to be much warmer than it is today. This would have caused it to look somewhat similar to Saturn, with yellowish haze over white clouds producing a pale yellow planet, except in certain regions where the absence of haze produces blueish tint. It may also have had dense rings, which I cannot be bothered to draw. The inner moon Proteus is visible to the bottom right of the image as a point source.

hey sorry ive been dead but ive been reading "neptune and triton", more specifically þe paper (chapter?) abt triton's capture and evolution. it mentions þe possibility of what is effectively a supercritical atmosphere of >100 bars of CH4/CO/N2 atop a hot sea of NH3/H2O. what þe fuck.????????????????
